Collection: SKX Caseback

Upgrade your custom build with our SKX Caseback, engineered for modders who want improved comfort, durability, and a premium finishing touch for their Seiko projects. Designed for smoother wrist wear and long-term reliability, this caseback is crafted from high-grade stainless steel and available in multiple finishes—such as brushed, polished, blasted, or engraved variants (depending on model). Its refined construction enhances both the look and feel of your SKX-style watch.

Precision-machined specifically for SKX007 cases, this caseback is fully compatible with SKX-style builds and works seamlessly with NH35, NH36, and other Seiko-based movements. Each unit features clean threading, secure gasket seating, and consistent depth ratings (water resistance depends on full build setup). The design ensures a tight, reliable fit that supports both everyday wear and dive-style modding projects.

Perfect for modders seeking a smoother profile, improved durability, or a custom aesthetic upgrade, the SKX Caseback delivers a professional finish and dependable performance to elevate any Seiko mod.
